Abstract

A wire drawing apparatus includes a carriage movable along an elongated frame. A chuck is mounted on the frame for holding one end of a wire, and a drawing die is mounted on the carriage for passing the wire therethrough. An actuating device is connected to the carriage for moving it along the frame to move the die along the wire so as to reduce the cross-section of the wire. A plurality of clamp devices are mounted on the frame and spaced along the length thereof for holding the wire. A plurality of drive devices are operatively connected respectively to the clamp devices to move them into and out of an operative position in a path of travel of the carriage where the clamp devices engage the wire. A plurality of position sensors are operatively connected respectively to the drive devices and sense the approaching of the carriage toward the respective clamp devices disposed adjacent thereto to produce a sensing signal in response to which each drive devices is operated to move the clamp device associated therewith out of its operative position.
